genfac3d Scilab Group Scilab Function genfac3d
NAME
genfac3d - compute facets of a 3D surface
CALLING SEQUENCE
[xx,yy,zz]=genfac3d(x,y,z,[mask])
PARAMETERS
xx,yy,zz : matrices of size (4,n-1xm-1). xx(:,i) ,yy(:,i) and zz(:,i)
are respectively the x-axis, y-axis and z-axis coordinates of
the 4 points of the ith four sided facet.
x : x-axis coordinates vector of size m.
y : y-axis coordinates vector of size n.
z : matrix of size (m,n). z(i,j) is the value of the surface at
the point (x(i),y(j)).
mask : boolean optional matrix with same size as z used to select
the entries of z to be represented by facets.
DESCRIPTION
genfac3d computes a four sided facets representation of a 3D surface
z=f(x,y) defined by x, y and z.
EXAMPLE
t=[0:0.3:2*%pi]'; z=sin(t)*cos(t');
[xx,yy,zz]=genfac3d(t,t,z);
plot3d(xx,yy,zz)
